Medium effects for hadron-tagged jets in proton-proton collisions
We study the medium modification factor Ipp within the light-cone path integral approach to induced gluon emission. We use parametrization of the running coupling αs(Q,T) which has a plateau around Q\sim \kappa T. We calculate Ipp with no free parameters using κ fitted to the LHC data on the nuclear modification factor RAA. We find that the theoretical multiplicity dependence of the ratio I_{pp}/\langle I_{pp}\rangle for 5.02 TeV pp collisions agrees reasonably with the recent preliminary data from ALICE [ALICE_Ipp].
